Godrej Dyna Surface-Mounted Hydraulic Door Closer with Integrated Hold Open Function

The Godrej Dyna Door Closer Hold Open Size 3 is engineered around a robust hydraulic mechanism, utilizing precision-machined adjustable valves to govern the door's closing and latching speeds. This hydraulic principle ensures controlled fluid resistance, preventing uncontrolled door movement and mitigating potential impact damage. The adjustable closing speed allows for tailored door closure rates from the maximum opening angle of 180 degrees down to approximately 15 degrees, while the adjustable latching speed precisely controls the final few degrees of closure, ensuring secure engagement with the strike plate without slamming. Crucially, the integrated hold-open function, enabled by a dedicated arm assembly, offers user convenience by securing the door in an open position at a user-defined angle, facilitating unimpeded traffic flow or material handling. This functionality is distinct from back-check or delayed action features, which are not present in this model. Constructed from a durable Aluminium Alloy body with a PU/Silver finish, the Dyna closer is designed for longevity, validated by a rigorous 100,000-cycle test rating, ensuring reliable performance over its 3-year warranty period. It is engineered for doors up to 60kg in weight and 950mm in width, aligning with its Size 3 power rating. Regarding compliance, it is important to note that the Godrej Dyna Door Closer Hold Open Size 3 is not fire-rated and does not carry specific EN1154 certifications. This positions the unit as an effective solution for general-purpose, controlled access applications on wood and metal doors where fire safety requirements or stringent international standard adherence are not the primary drivers. Its non-handed design simplifies specification and installation, enhancing its versatility across various architectural layouts.
